... First, apply the above equation about the x axis. We have, Ix = (3 kg)(9 m2)+(2 kg)(9 m2)+(2 kg)(9 m2)+(4kg)(9 m2) = 99.0 kg m2. About the y axis, we have Iy = (3 kg)(4 m2) + (2 kg)(4 m2) + (2 kg)(4 m2) + (4kg)(4 m2) = 44.0 kg m2. The distance, r, (from an axis through O and perpendicular to the pag ...

... 33. The force to produce the required torque is Fwrench = /L = (80 m · N)/(0.30 m) = 2.7 102 N. Because this torque is balanced by the torque produced by the bolt on the wrench, an equal torque is produced on the bolt. Because there are six points where a force is applied to the bolt, we have Fbo ...

Precession
Precession is a change in the orientation of the rotational axis of a rotating body. In an appropriate reference frame it can be defined as a change in the first Euler angle, whereas the third Euler angle defines the rotation itself. In other words, the axis of rotation of a precessing body itself rotates around another axis. A motion in which the second Euler angle changes is called nutation. In physics, there are two types of precession: torque-free and torque-induced.In astronomy, ""precession"" refers to any of several slow changes in an astronomical body's rotational or orbital parameters, and especially to Earth's precession of the equinoxes.
